It is rumored that all farms in Europe rely on chemical fertilizers to grow their land, but you are wrong. Almost all of Europe (EU) is extremely strict in regulating the use of fertilizers.
At the end of the century, the European Union issued the Nitrates Directive 91 676 EEC (Directive 91 676 EEC on the protection of water from nitrate contamination in agriculture), with the aim of regulating and reducing the overuse of sewage, livestock and poultry waste and fertilisers, and developing and implementing action plans for vulnerable areas to reduce water pollution caused by nitrates. EU fertilizer products are classified into functional categories (PFCs) that are different from other agricultural products, and under these conditions must comply with specific safety and quality requirements applicable to their different intended uses.
At the same time, the raw materials for fertilizer products in the EU are also divided into different categories (CMCs), and each material should meet specific process requirements and control mechanisms. Of course, their fertilizer producers are free to choose whether they want to register and sell their fertilizers at EU level or at member state level within the EU. These initiatives reflect the importance that the EU attaches to environmental protection and resource management. Therefore, most farms began to use the method of green seedling fertilizer provided by agricultural professionals, mainly by planting green plants to increase soil fertility.
Green manure is a kind of biological fertilizer source with very complete nutrients, and planting green manure is not only an effective way to increase the fertilizer source, but also has a great effect on improving the soil. Green manure can provide rich nutrients for the soil, because the young stems and leaves of various green manure contain extremely high nitrogen, phosphorus, potassium, magnesium, calcium and other nutrients, which is a good organic fertilizer.
At present, the countries that use green manure the most are mainly large farms such as France, the Netherlands, and Germany. Every year, they will give priority to planting agricultural green manure before planting crops, and when it grows to about 15 25 centimeters, they use agricultural tractor-drawn special crushing equipment to plough the ground, so as to improve the structure of the soil, improve the organic matter of the soil, and I heard that there are many earthworms in the field.
In such an operation scene, it is first a green manure, and the land becomes fertile black soil as soon as it is turned over. Isn't it interesting to think of such a scene? So many friends will ask, why is it called green manure? Isn't this just grass? Indeed, your clever mind guessed that this is grass, but people don't grow ordinary grass.
In fact, these are leguminous crops, such as clover, alfalfa, peas, soybeans, mung beans, etc., because leguminous crops have an important nitrogen fixation effect, which can convert air nitrogen to the roots, and return to the field through ploughing, which can improve soil fertility very efficiently.
How exactly is green manure grown? This kind of green manure is sown after the autumn harvest, generally after 2 to 3 months of growth, before the arrival of winter, you can plough the ground, and you can plant other crops normally in the spring of the next year. The other is the fallow mode, which does not plant crops for one to two years, and only uses green manure from the planting base to improve the soil. Of course, the cultivation of green manure is also very particular.
The first step is to break the green manure first, and the second step is to plow the ground and turn the green manure deep into the ground. Most farms in France use a distributed operation model, first using tractors to pull rotary tillers for crushing, and then ploughing.
Such a combination of front and back, five in the front and seven in the back, can complete the green manure ploughing of hundreds of acres of land in one day. The other combination is directly in the back of the nine-plus-five combination mode, such a model is quite explosive in the visual view of the drone, and a farming operation can be misunderstood as a large-scale engineering construction operation.
The Dutch model of green manure and mud is mostly an integrated model. They are the opposite of the German towed rotary tiller, the Netherlands is the tractor in front of the rotary tiller and crushing, the rear end is directly ploughing the ground, the tractor passes through the green manure and black soil instantly present two scenes.
What's even more interesting is that some of them have a climbing plow module behind the dirt. This is what some farmers in Germany do, also with combination ploughs. A German high-horsepower tractor can tow a combination of 16 rotary ploughs.
In such an operating environment, thousands of acres of green manure farmland can be easily completed, which is the green manure farming mode of large European farms.
The main purpose of sharing this case is to let everyone understand that in addition to allowing insect eggs to pop up more pests and diseases in the coming year, straw will also make it difficult for the roots of crops to penetrate into the soil to absorb nutrients.
Some of the straw returning to the field also appeared in the mushroom community, which proves that the chemical reaction between the soil and the straw has produced a lot of heat and soil pH imbalance, which not only can not let the fertilizer can not enter the soil evenly, but also will have the situation of fertilizer accumulation and root burning (root rot). Not to mention whether the straw of the year can be decomposed by the field, I believe that you can still find the straw three years ago in the field, friends in the city do not believe that you can find a pot to plant a plant with tenacious vitality, and add some crop straw every year to try whether your plant can grow well!
Straw in the soil not only does not make the soil more loose, it will only cause cavities in the soil and straw so that crop roots can not penetrate into the soil, and in severe cases, it will only make more root-eating insects appear in the ground, and you seem to have no other choice but to use pesticides endlessly. Of course, the harvest will also surprise you, because in addition to growing crops of varying heights, such land provides the basis for the wild growth of tenacious weeds. Secondly, straw can cause the soil to be too loose and too much water, which may directly affect the root health of plants.
If the soil is too loose, it may not be able to provide sufficient support for the plants, and the plants may fall. Alas, I don't know which great clever man made our country's agriculture use this most unfavorable way of crop development for farming. So don't think that developed countries are all farming with chemical fertilizers, but we are the way to cultivate the land in a way other than chemical fertilizers. In fact, as early as a thousand years ago, China summed up a set of cultivation methods, before planting the land, there is a set of professional cultivation logic, but all this was learned by foreigners who could not even grow leguminous plants in the Middle Ages. Now let's compare and look at the large-scale agricultural production areas at home and abroad, how many farms are adhering to the way of cultivating land? Recently, a certain place in China has been pushing high standards of farmland, what is high standards? Is it a high standard to repair roads, fields, and canals? If the soil is not improved, it is impossible to grow high-quality agricultural products, and at a glance it is a high-standard Baokan to prevent landslides, and dig out the loess in ancient times to farm? What high standard is this? There was a time when the soil was poor in nutrients in our country, and when we looked back, the trees on the mountains did not grow much! I suggest that all high-standard farmland should not be planted in the first three years, and sooner or later you will have to fool the public with green paint! Plant some green manure first, improve the soil, and then grow food, and in the third year, the land will form fertile soil, and you will definitely be able to grow high-quality crops.
Of course, this process should be undertaken by the construction unit, and the completion of high-standard soil is also one of the construction projects. Finally, I suggest that the acceptance of high-standard farmland must learn from foreign ready-made results, not to listen to some experts, to take the assessment of soil as an important indicator, unqualified soil will not be accepted, we hope that our country has the best field in the world. I don't know if you agree with it. Well, follow Mr. Huang to show you through the new model of global agriculture.
